PHP中的hash函数各种algo的执行效率和结果比较示例
测试代码：
1 public function test(Request $request) 2 { 3 $algos = hash_algos(); 4 $plain = (string)time(); 5 $result = []; 6 foreach ($algos as $algo) { 7 // 这是一个取当前微秒时间戳的方法，返回float 8 $start = \app\util\Utils::microtimeFloat(); 9 for ($i = 0; $i < 500000; $i++) { 10 $hash = hash($algo, $plain); 11 } 12 $end = \app\util\Utils::microtimeFloat(); 13 $duration = $end - $start; 14 $result[] = [ 15 'algo' => $algo, 16 'plain' => $plain, 17 'hash' => $hash, 18 'hash_length' => mb_strlen($hash), 19 'duration' => $duration, 20 ]; 21 } 22 usort($result, function ($a, $b) { 23 if ($a['duration'] == $b['duration']) return 0; 24 return ($a['duration'] < $b['duration']) ? -1 : 1; 25 }); 26 return json($result); 27 }
简单说明：
第3行hash_algo()函数返回由当前系统所有已注册的哈希算法组成的数组，不同的环境下hash_algo()函数的返回值可能不相同；
第9行可以调整循环次数来调整程序执行时间；
第10行就是具体hash()函数的用法。
补充一点，每次的执行结果（排序）不完全相同，但是变化不会太大。
